3.2.6, 3.4.6, 3.6.0, and 3.7.0 Security Advisory

Thursday, June 24, 2010

Summary
=======
Bugzilla is a Web-based bug-tracking system used by a large number of
software projects. The following security issues have been discovered
in Bugzilla:
* Everybody could search for time-tracking information, not just
members of the timetrackinggroup.
* Under suexec, "localconfig" was world-readable, meaning that
local users with shell access to the Bugzilla server may have
been able to see the database password and the site_wide_secret.
All affected installations are encouraged to upgrade as soon as
possible.
Vulnerability Details
=====================
Class: Remote Information Disclosure
Versions: 2.17.1 to 3.2.6, 3.3.1 to 3.4.6, 3.5.1 to 3.6, 3.7
Fixed In: 3.2.7, 3.4.7, 3.6.1, 3.7.1
Description: Normally, information about time-tracking (estimated
hours, actual hours, hours worked, and deadlines) is
restricted to users in the "time-tracking group".
However, any user was able, by crafting their own
search URL, to search for bugs based using those
fields as criteria, thus possibly exposing sensitive
time-tracking information by a user seeing that a bug
matched their search.

CVE Number: CVE-2010-1204
Class: Local Information Disclosure
Versions: 3.5.1 to 3.6, 3.7
Fixed In: 3.6.1, 3.7.1
Description: If $use_suexec was set to "1" in the localconfig file,
then the localconfig file's permissions were set as
world-readable by checksetup.pl. This allowed any user
with local shell access to see the contents of the file,
including the database password and the site_wide_secret
variable used for CSRF protection.
